Reactive polyurethane Hot-melt Adhesives (PUR), its chemical structure of the NCO functional groups, and the moisture in the air crosslinking reaction, the formation of a great molecular weight of PU structure.
Solid at room temperature before use must be put to the oven or other heating equipment to a certain processing temperature (about 80-150 ℃), then the processing, so-called reactive hot melt adhesives.
- Long operation time, fast curing speed, soft after curing, low temperature operation and high initial adhesion. After curing process, the bonding result shows high strength and toughness.
- Applicable for lamination of TPU films, fabric to fabric, PVC sheets, PU sheets and fabric base lamination. Widely used in all kinds of clothing, light bags, bags & cases, medical products, water bladders, inflated beds and industrial fabrics, etc.
